You are on your own in terms of checking the circuitry on your machine and your probe, but I am operating without the SSR with one-wire probe outputs (the small one is NPN) by connecting to the input terminal of the pair that is pulled up to rail voltage (which normally connects to the other terminal that is GND). NO vs. NC was handled in PathPilot’s active/passive probe setting. I grabbed 24V from an existing power rail since the amperage on this is negligible. I dropped probe speeds to deal with getting errors during rapid successions of probe operations until I isolate what the culprit is.
